If it's safe to heat the bearing, heat it, and cool off the shaft with a wet rag immediately, so it shrinks.

Otherwise, use a cutoff wheel. A torch can be used to burn off the bearing, if you know how to do it.

The bearing is no longer there completely rusted out It's the pully I can't get off the shaft.

You may need to soak with PB Blaster or something better for several days - below is a reprint from a previous post of mine.

I am not familiar with the pulley on your particular application but I have used an air chisel with a blunt bit driving from behind with great success OR if it is a steel pulley, drill a hole to accept a 5/16" bolt on each side of the center hub out far enough to get a washer and nut on, drill matching holes in a pc. of 1/2" or thicker bar stock in the 1-1/2" wide range. run a bolt into the center of the crankshaft at least an inch and leave it 1/2" above pulley or insert a pc of round stock for a spacer between end of crankshaft and face of pulley, run hardened bolts thru the bar you drilled and thru the pulley, put a washer and nut on the back side, tighten both bolts evenly, hit the center of the bar a good sharp rap may help when there is a lot of tension on the bolts.

Good luck,

Walt, if I understand this correctly, the 1/2" bar stock backside rests against the bolt in the crankshaft. The two bolts which pass through the barstock would have to be long enough to go through the barstock, the air space between the barstock and the pulley and then out the back of the pulley enough to get nuts on, or at least 2" long?

A very, very olde machinist tip, is to heat the shaft warm enough so that bee's wax, or candle wax will melt and seep into the shaft. let it cool, and the next day you should have results.

That is right baymee.
